What Is a NAICS Code in Federal Contracting?

Summary: A NAICS code classifies the industry associated with a federal contract. The North American Industry Classification System uses up to six digits, with more digits meaning a more specific industry. In federal contracting, each award carries a NAICS code describing the type of work.

What NAICS classifies

NAICS describes the industry of the work being performed. It is a North American standard used well beyond procurement, which is part of its value: it lets you compare federal contracting activity against broader industry context using the same classification everyone else uses.

How NAICS codes are structured

NAICS codes are hierarchical and can be up to six digits. The first two digits indicate a broad sector, and each additional digit narrows the classification. A six-digit code is a specific industry; a two-digit code is a whole sector. Award records typically carry the most specific code available.

NAICS in federal contracting specifically

When the government issues a solicitation, it assigns a NAICS code that reflects the primary purpose of the requirement. That code influences which businesses are considered for small-business purposes and shapes how the award is categorized. On an award record, the NAICS code tells you the industry the government assigned to that contract.

NAICS vs PSC

NAICS and PSC are complementary. NAICS answers 'what industry?' and PSC answers 'what was bought?'. Using both gives a fuller picture: for example, a single IT services award has an IT-related NAICS for the contractor's industry and an IT-related PSC for the service delivered.

Why the assigned NAICS matters competitively

The NAICS code on a solicitation is not just a label — it can affect who competes. NAICS codes are tied to size standards that determine whether a business qualifies as small for a given requirement, which in turn shapes set-aside decisions. That means the same kind of work can attract a different field of competitors depending on the NAICS the agency assigns. For a contractor, knowing the NAICS codes the government tends to use for your work helps you anticipate the competitive landscape and position accordingly.

Using NAICS to map a market

Browsing awards by NAICS turns the classification into a market map. Pick the industry code that describes your work and you can see which agencies buy in that industry, which companies win there, and how activity has trended. Because NAICS is a shared standard used far beyond procurement, it also lets you connect federal activity to broader industry data using the same vocabulary.

Common NAICS mistakes

Treating NAICS as a description of the deliverable — that is what PSC does.
Assuming one award maps to only one industry when complex work can span several.
Ignoring the size-standard implications of the assigned code.

Frequently asked questions

How many digits is a NAICS code?

Up to six. More digits indicate a more specific industry; the first two indicate a broad sector.

Does the NAICS code affect small-business eligibility?

Yes — NAICS codes are tied to size standards that influence whether a business counts as small for a given requirement.
